In this article I discuss the misfits problem, a practical issue that arises in random treatment assignment whenever observations can’t be neatly distributed among treatments. I also introduce the randtreat command, which ...

We exploit the exogenous characteristic of random freshmen course assignment in a large Chilean university to identify the causal effect of teachers and their qualitative characteristics over students’ major choice. ...

The matroid secretary problem admits several variants according to the order in which the matroid’s elements are presented and how the elements are assigned weights. As the main result of this article, we devise the first ...

We propose a new metaheuristic algorithm to find “good” solutions for the assignment of small treatment-control groups, minimising the random resource. Using simulated cases, we achieved 100% groups with equivalence levels ...
